True Strike: if Twin Snakes and Dragon Kick is up, I will use after bootshine from the rear, and I do notice the 5% chance to crit. It does hit harder than Twin Snakes and I use it all the time.

Haymaker: This procs in some fights more than others and unless I'm about to lose GL I will always use it. It's 40TP and 170 potency with a short slow. Why would you pass that up?

Fists of Wind: Although mostly just for convenience running around, I've found this to be useful in helping attacks connect when mobs are being kited, and also helps reduce the margin of error running out of Titan HM final phase Plumes.

I notice a lot of MNKs that I've partied with don't like to switch their stances. I switch into Fists of Earth in many situations to mitigate damage. I haven't tested this to be sure if Fists of Earth works with Aerial Blast and Earthen Fury.
